The Environmental Protection Agency (EPA) is proposing approval of a State Implementation Plan (SIP) revision submitted by the State of Missouri on January 15, 2019 and supplemented by letter on July 11, 2019. Missouri requests that the EPA remove from its SIP a rule related to control of emissions from bakery ovens in St. Louis City and Jefferson, St. Charles, Franklin, and St. Louis Counties. The EPA's proposed approval of this rule revision is in accordance with the requirements of the Clean Air Act (CAA).
